Apparatus for reading an RFID tag includes an RF-blocking enclosure having a port and adapted to receive through the port a non-RFID-active object having an RFID tag affixed thereto. An RFID reader has a reader antenna located outside the enclosure. The antenna transmits an RF downlink signal in a particular direction. An RF grating is arranged between the reader antenna and the port so that, after the enclosure receives the object having the tag, the port is located in the transmit direction from the reader antenna, and RF energy transmitted from the reader antenna has a selected linear polarization after passing through the grating.

An automated service discovery and monitoring utility employs automatically generated policies (rules) for monitoring network health of a service based on network discovery using flow data derived from transmissions sent over segments between computing components defining the service. An interactive discovery application employs flow data based on transmissions associated with a service. Analysis of the flow data identifies associated components from inspection of the transmissions. Iterative component selection allows network traversal of components based on flow data of the segments used for providing the service. The interactive service discovery therefore identifies associated components (servers) and segments based on flow data, rather than topology, rendering the flow data to allow a user to make an informed selection of segments and components for inclusion in a service, and generates a set of policies (rules) based on the discovered service dependencies for monitoring various metrics for the components providing the monitored service.

A method is provided in one example embodiment and includes evaluating a first plurality of messages from a media server configured to receive a media stream. The first plurality of messages is indicative of an active state for the media server. The method also includes detecting an anomaly associated with a portion of the first plurality of messages. The anomaly is associated with a failure of the media server. The method can also include activating a failover media server to receive the media stream based on the anomaly, and evaluating a second plurality of messages. The second plurality of messages is indicative of a resumed active state for the media server that experienced the failure. The failover media server can be deactivated based on the resumed active state. Media metadata can be communicated from the failover media server to the media server that experienced the failure.

An electroluminescent (EL) subpixel driven by a digital-drive scheme has a readout transistor driven by a current source when the drive transistor is non-conducting. This produces an emitter-voltage signal from which an aging signal representing the efficiency of the EL emitter can be computed. The aging signal is used to determine the loss in current of the subpixel when active, and an input signal is adjusted to provide increased on-time to compensate for voltage rise and efficiency loss of the EL emitter. Variations due to temperature can also be compensated for.

A method of displaying a video of a scene on a display with reduced motion blur includes: providing the video of a scene having first subframes that have a first input rate and second subframes that have a second input rate, wherein the first subframes correspond to a first region of the display and the second subframes correspond to a second region of the display; and selectively providing the first and second subframes to corresponding regions in the display, and providing the first region of the display with a first update rate and the second region of the display with a second update rate, wherein the first update rate is greater than the second update rate, so that the displayed image has reduced motion blur.
摘要:
A self-sustaining ultra-high frequency oscillator and method enable the ability to oscillate and output a signal. A balanced bridge circuit is utilized to null an embedding background response. A first vibrating nanoelectromechanical (NEMS) beam resonator is part of one of the branches of the balanced bridge circuit and determines the frequency of the oscillator's output signal. A feedback loop establishes and sets oscillation conditions of the oscillator's signal. Further, the feedback loop connects an output of the first resonator to an input of the balanced bridge circuit.
摘要:
A method and apparatus for stream aggregation in a multiprotocol label switching network environment. According to one embodiment, the method comprises receiving a label assignment request that includes an identification of a path followed by the label assignment request through the network and determining whether the path has been used by any of a plurality of previous label assignment requests. A new label is assigned for the path if the path has not been used by any of the plurality of previous label assignment requests. Otherwise, a previously assigned label is assigned.
